Polystyrene-supported copper(II) N,N,N′,N′-tetraethyldiethylenetriamine [Cu(II)-TEDETA] complexes efficiently catalyzed the oxidative homocoupling of terminal alkynes under air to give the corresponding 1,3-diynes in very good yield. The catalyst was easily recovered by simple filtration and reused eight times without significant loss of catalytic activity.
